Step 5: Soldering Components Step 6 of 7

Next, I soldered the wires from the circuit board to their respective components. I soldered wires to the input audio jack. Afterwards, I soldered wires going through the potentiometer and into the speaker. Then I connected the LED to the circuit board. Lastly, I soldered the red wire from the 9v battery clip to the rocker switch, with a wire coming off the second terminal of the switch going to the circuit board.

Here is what the wired up amplifier looks like:

(Notice that the wires on the audio jack are soldered to the last and middle lugs on the "switch" side of the jack.)
